Comparative Study of Multiple Regression Model with Curvefit Model for The Prediction of Solar Radiation in Mubi Town Adamawa State, Nigeria

The sun emits solar radiation, which is critical for researchers working on renewable energy technology that provides ecologically favorable power systems. This research created a new model to forecast DHSR the Mubi metropolitan area in Adamawa State, Nigeria. Data this study were obtained from National Aeronautics and Space Administration (NASA) over 22-year period (2000 – 2021). When was employed as an output, requested values air temperature (Tai) relative humidity (Rhi). MATHLAB curve fitting program used create mathematical model. validated using five statistical methods study: MSE (mean square error); SSE (sum of errors); RMSE, Chi-square error (X2), absolute fraction variance (R2) are 0.0005, 0.0064, 0.0231, 0.0011kWh/m2/day, 0.9998, respectively.
